值得了解
Founded by Dr Adolf Peretti. GRS applies proprietary colour descriptions such as GRS-type pigeon's blood and GRS-type royal blue, which are the laboratory's own terminology rather than an industry-wide standard. Laboratories operate in Switzerland, France, Hong Kong, Thailand and the United States.
